How do you calculate the body mass index? BMI is calculated by the following formula. The weight is divided by the square of the length. As an example we can take a person having a weight of 70 kg and a length of 175 cm. The calculation is 70 divided by the multiplication of 175cm. The outcome ......

There is underweight if the index is less than 18.5. The recommended weight we find in values between 18.6 and 24.9. There is obesity in values between 25.0 and 29.9. If there is an index greater than 30, then we call this obesity.

This calculation applies to men, women and children. For the interpretation of the BMI for children it is important to realise that they have other outcome. For example a boy at 7 years old a healthy BMI lays between 14 and 18.
